Phoebe Elizabeth Barnard

Phoebe Barnard is an American global change scientist and professor of conservation biology and environmental futures at the University of Washington. Barnard has written more than 180 publications on the vulnerability of biodiversity and ecosystems to climate and land use change. She is a member of the Club of Rome's Planetary Emergency Partnership, one of five core co-authors of the 2019 paper World Scientists’ Warning of a Climate Emergency, lead author of the action-focused 2021 World Scientists' Warnings into Action: Local to Global, second co-author of the 2023 World Scientists' Warning: the Behavioural Crisis Driving Ecological Overshoot, a provocative collaboration of scientists, educators and global marketing strategists, and major co-author of Earth at Risk: an Urgent Call to End the Age of Destruction and Forge a Just and Sustainable Future, a western-Indigenous collaboration.

Impatient with warnings, Barnard has focused on bold global actions. In 2021, she co-founded and led the Stable Planet Alliance, a global coalition of organizations working to reduce ecological overshoot. In 2022, she and John D. Liu started the Global Restoration Collaborative, a global coalition of organizations working to restore ecosystems, climate and biodiversity while upskilling and co-designing with leaders from youth, women, Indigenous and technical networks. Her ideas on the crossroads of civilization and collaborative solutions have influenced organizational plans and visions of the EcoRestoration Alliance, Global Evergreening Alliance, Institute for Ecological Civilization, Planetary Emergency Partnership and others. Barnard has mentored hundreds of young professionals, especially women conservation scientists, across Africa, the Americas, Europe and Asia. Barnard and husband John Bowey have co-produced a four-film 2025 global documentary series, The Climate Restorers, exploring the fast-changing world of climate and ecosystem restoration solutions at these crossroads.
